Download Teaching Materials (PDF)

These teaching materials
will prepare you to help your students investigate the topics in
the on-line science lessons. Even if you do not have much experience
in using web-based activities in your science classes, the directions
here are easy to follow.

The lesson files are provided in PDF format. If you
do not have Adobe Acrobat Reader installed on your computer, download
it now so you can read and print these files.

You may make as many copies of the Student Activity
Books as you need. Students will find it easier to collect data
and information using an activity book. Books contain specific directions,
spaces for answers, graphs, and maps.
